Press TV: A report by Iran’s Mehr news agency last week showed that bitcoin miners were using power in buildings and properties that enjoy a lower price for electricity, including factories, greenhouses, government offices and mosques.
…A spokesman of Iran’s Ministry of Energy said on Monday that the country’s power grid had become unstable as a result of increased mining of cryptocurrencies.
Bitcoin mining in a mosque may seem outré but at least it’s not money lenders in the mosque. In fact, Bitcoin is halal, at least according to one source (quoted here):
As a payment network, Bitcoin is halal. In fact, Bitcoin goes beyond what more conventional closed banking networks offer. Unlike conventional bank networks which use private ledgers where there’s no guarantee that the originator actually owns the underlying assets, Bitcoin guarantees with mathematical certainty that the originator of the transfer owns the underlying assets. Conventional banks operate using the principle of fractional reserve, which is prohibited in Islam.
Muhammad was a merchant and much more open to business than some traditional Christian interpretations. For example, compare Jesus, “it is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God” with one of Muhammad’s sayings:
Abu Said related that the Prophet said: The truthful and trustworthy businessman will be in the company of Prophets, saints and martyrs on the Day of Judgment. (Darimi, Tirmidhi)
